I just bought a Skytech 3301P2 wireless thermostat to install on my VistaFlame VF55. The receiver has 2 black wires that look like they are to be plugged into the back of the stove. Neither of the black wires or the plug in the back of the stove note which wire plugs into which port. Does this mean that I can put either wire in either port? Also, I want to run the stove in high/low mode. Currently the stove is set on manual mode, should I turn on the stove first and change the setting to high/low and select the heat levelbefore turning on the thermostat? And last question...What does the "Learn" button do on the receiver?
